Toshiba 32A30 32" TV Questions & Answers

I have been seeing a lot of Toshiba remote "eyes" (the infra-red receiver inside the TV) fail recently. If several known good remotes cannot control the TV then the IR receiver will have to be replaced. If you have no experience soldering and unsoldering PC boards then have a qualified tech handle it for you.

It will work again if you take it apart and clean the entire circuit board with alcohol. Clean also the keypad. Let dry and put back together. Some have screws holding them together and some have plastic clips that you have to take a knife to pry apart and unclip.

Your TVs vertical swee sction has failed. All CRT based TVs have both vertical and horizontal sweep sections to sweep the picture both in vertical and horizontal direction to display it on the picture tube screen. This process is otherwise called as scanning. If vertical scan section fails, you will see a horizontal line at the middle of the screen and if horizontal scan fails, you will see a vertical line on the middle of the screen.
You have to open your TV to retify this fault, as the fault lies in the internal circuit board. Open it after disconnecting it from the mains wall socket, and locate the vertical output section inside. It is very easy to locate. On opening you can see a coil fitted on the neck of the picture tube, called deflection yoke, and there will be four wires from it goes to the main board. Out of which two of them will be thick, and the other twos will be thin. The thick wires are usually colour coded as red and blue. Just follow the two thin wires. You will reach to a plung in socket to which these four wires together connected. Turn upside down the circuit board, and follow the print track through the print side of the above said two thin wires connection goes. it will go to the vertical output section.
Before doing any thing, first look into the circut board for any loose or bad solderings are there. It is a common fault that this section have loose solderings on it, because most of the components will heat up while working. Repeated heating and cooling, make loose soderings to emerge.
Resolder all the suspected points, as loose solderings will be microscopic,a nd acnnot be detected very easly. We in the service field also will fist do this.
Usually vertical output section is composed of an IC related circuit. Solder all pins of that Ic first and feel the effect. If this does not help, desolder the IC out of the board, will be screwed on to a metal heatsink, go for the same type and number. Replacing the IC will solve your problem.

try to check your remote sensor if working.Using your cellphone camera,point your sensor on your cellphone camera you should see a illumination of light on your remote control once you press the a button on your remote..if not try to fit your battery tou your remote there might be a loose contact on battery terminals..or open the casing of your remote control.visually inspect the battery terminals from a loose contact and corrosion.if this dont solve your problem,replace the crystal oscillator of the remote..it is the color orange square in shape with two terminals soldered near the ic..it is labeled with frequency....

your remote is old and needs to be cleaned and rebuttoned(you can do this yourself) open up the battery panel and look for small screws to take of the case. you need to dust it out with compressed air. and reline the buttons. when you push down on the power button it probbaly is not making complete contact with the button, take a small thing and poke the power button without the buttons on. see if that works. if it turns on right away with direct pressure to the power switch then you just need to make sure your buttons are making complete contact. if that dont work then your circuit is screwed. you need a new remote or a new tv.

sounds like you could be right- possible fix----try removing battries and re-placing with brand new ones also pressing the on/off button while holding down the 5 button can reset the remote - I have never tried this myself but I was told by the manufactors that this is the way to do this - if you can belive that- worth a go - nothing to loose everything to gain.B/O/L------P.

You'll have to contact Toshiba's part distributor in order to purchase a replacement remote. The company is Fox International and their number is 800-321-6993.
